The air pressure for a tire is 109 kPa. What is this pressure in atmosphere? The pressure of the earth's atmosphere at sea level is 14.7 lb/in^2. What is the pressure when expressed in kg/m^2? The surface of a planet has ...
Because atmospheric pressure is relatively constant, the pressure in the lungs must change to create airflow between the lungs and the outside environment. During inhalation (inspiration), the diaphragm and supporting muscles (intercostal muscles) contract, which results in an expansion of the thoracic...
What is this pressure expressed in torr? Convert a gas pressure of 485 cmHg to atmospheres. Atmospheric pressure is measured at 766.82 mmHg. What is the pressure in: \\ A. torr? B. atm? C. kPa? Perform the conversion: 367 torr to in.Hg Convert the pressures as indicated. a. 699 m...
collapsedaround 3.7 billion years ago, and it lost its atmosphere. Now, Mars has a very thin atmosphere: the atmospheric pressure on theMartian surfaceaverages 600 pascals (0.087 psi; 6.0 mbar), about only 0.6% of Earth’s mean sea level pressure of 101.3 kilopascals (14.69 psi; 1.013 bar...
(mmHg) is a unit of pressure typically used in measuring blood pressure. The kilopascal (kPa), which is 1,000 pascals, is a metric pressure unit used to gauge a variety of pressures, from atmospheric to internal pressure. Millimeters of mercury can be converted to kilopascals using simple ...
Multiply this answer by the pressure drop across the pipe, measured in pascals. With a pressure drop, for instance, of 80,000 pascals, 0.0025 x 80,000 = 200. Step 3 Multiply the constant pi by the answer to Step 1: 3.142 x 0.0025 = 0.00785. This answer is the pipe's cross-sectiona...
Convert the pressure the fan creates, measured in pascals, to feet of water by dividing by 2,989. Each inch of water contains 249 pascals, and each foot of water contains 2,989 pascals. If the fan adds a pressure of, for instance, 1,000 pascals: 1,000 ÷ 2,989 = 0.335. ...
In a vacuum environment, the absolute pressure of the gas is much lower than the typical atmospheric pressure at sea level, which is about 101,325 pascals (Pa) or 14.7 pounds per square inch (psi). The atmosphere is mostly nitrogen and oxygen, but when dealing with vacuum chambers, we mu...
3. Normal atmospheric pressure at sea level is generally considered to be equal to the pressure exerted by a column of mercury 760mm high. Calculate the corresponding pressure in inches of mercury and in Pascals. 4. The hydraulic lift in a service station is capable of raising cars with a...
Thebarometer works bybalancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales. Atmospheric pressure is basically the weight of air in the atmosphere above the reservoir, so the level of mercury continues to change until the weight of mercury ...
